Eustress and Malondialdehyde (Mda): Role of Panax Ginseng: Randomized, Placebo Controlled Prospective Study

Objective: the present study aimed at evaluating the effect of panax ginseng on malondialdehyde (mda) serum levels during eustress on healthy volunteers. method: in this study, 65 healthy volunteers were recruited from students of a medical school, with the mean age of 22.61±3.63 years. the volunteers were divided into 2 groups: group a included 35 participants who were treated by panax ginseng 500 mg/day, which was regarded as the treated group; group b included 30 participants treated by placebo 500 mg/day, which was regarded as the control group. baseline data were obtained and then one month after the study, the participants were followed with respect to induction of psychological stress through daily psychomotor performance task and visual working memory accuracy testing. stress was assessed by malondialdehyde (mda) serum levels. results: the participants in the control group showed significant increases in mda serum levels (p = 0.0004), which were related to significant increases in perceived stress scale from p<0.0001, while panax ginseng led to significant reduction in mda serum levels (p<0.01), with significant increase in perceived stress scale (p = 0.02). conclusion: panax ginseng produced significant reduction in oxidative stress and augmented eustress level in healthy volunteers 1 month after therapy.
